Bitcoin services attacked

High interest in Bitcoin has seen providers of associated services suffer. Sites have been slow, and at least two services have confirmed that have suffered from malicious attacks:


Mt.Gox has been suffering from its worst trading lag ever, 502 errors, and at one point some users were not able to log in their account. The culprit is a major DDoS attack against Mt.Gox.

Since yesterday, we are continuing to experience a DDoS attack like we have never seen. While we are being protected by companies like Prolexic, the sheer volume of this DDoS left us scrambling to fine-tune the system every few hours to make sure that things don’t go beyond a few 502 error pages and trading lag.

The Instawallet service is suspended indefinitely until we are able to develop an alternative architecture.


Our database was fraudulently accessed, due to the very nature of Instawallet it is impossible to reopen the service as-is.

In the next few days we are going to open the claim process for Instawallet balance holders to claim the funds they had stored before the service interruption.

Mt. Gox speculated that the attacks were performed by short sellers, attempting to weaken confidence in the crpytocurrency in order to buy it more cheaply and make quick gains.
